The electric drive of external rear-view mirrors – general information and check of serviceability of functioning

In most cases for the drive of a lateral rear-view mirror two electric motors are used: one provides adjustment of provision of a mirror in the vertical plane, the second – in horizontal.

The switch of control of the electric drive is equipped with the selector knot providing a choice of the direction of giving of tension (on right or on the left mirror). Without starting the engine, turn the ignition key in the situation ON, lower door glasses and test all modes of functioning of the electric drive of both lateral mirrors.

Attentively listen to the sounds made by electric motors of the drive of mirrors.

If aurally the motor works regularly, however the mirror does not change the situation, perhaps, defect of the driving mechanism in a mirror takes place. Remove the corresponding mirror and sort it for search of a cause of failure.

If a safety lock as it should be, remove assembly of the switch of management from the support, without disconnecting from it an electrical wiring. Include ignition and check existence of tension on the switch – tension has to take place on one of plugs. If tension is absent, check a chain electrical wiring on a site between the switch and the panel of safety locks for existence of breaks and short circuit.

If tension takes place, disconnect an electrical wiring from the switch. Check the switch for existence of conductivity in all its provisions. If conductivity is absent, replace the switch.

Again connect an electrical wiring to the switch. Find the wire going from the switch on weight. Without disconnecting the switch, establish a wire crossing point between the plug of this wire and weight. If now motors start working regularly, replace contact knot of grounding.

If the drive still does not function, remove the corresponding mirror and check a chain in it for existence of tension (at the included ignition and appropriately installed switch selector). Serially transfer the switch to all its possible provisions – in each of them (except neutral [OFF]) tension has to take place on one of mirror electric drive chain wires.

If tension is absent at all provisions of the switch, check a chain electrical wiring on a site between a mirror and the switch for existence of breaks and short circuits.

If tension takes place, remove a mirror and check serviceability of functioning of its drive by direct connection to the battery by means of wires crossing points. Replace a faulty mirror (see the Head Kuzov).
